简介
Background
Only human epidermal growth factor receptor (HER)2 status determined by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) has been validated to predict efficacy of HER2-targeting antibody-drug-conjugate trastuzumab emtansine (T-DM1). We propose molecular imaging to explore intra-/interpatient heterogeneity in HER2 mapping of metastatic disease and to identify patients unlikely to benefit from T-DM1.
Patients and methods
HER2-positive mBC patients with IHC3+ or FISH ≥2.2 scheduled for T-DM1 underwent a pretreatment HER2-positron emission tomography (PET)/computed tomography (CT) with 89Zr-trastuzumab. [18F]2-fluoro-2-deoxy-D-glucose (FDG)–PET/CT was performed at baseline and before T-DM1 cycle 2. Patients were grouped into four HER2–PET/CT patterns according to the proportion of FDG-avid tumor load showing relevant 89Zr-trastuzumab uptake …
